This is the concept of sequences and series. To solve the question we proceed as follows:
2] T=-4n-3
to get the 11th term we substitute n=11 in the expression and simplify. Thus, plugging in n=11 we obtain:
T=-4(11)-3
T=-44-3
T=-47
thus the 11th term is -47
3] General term is T=n²-1. The 7th term will be evaluated as above:
plug in n=7 in the expression and simplify:
T7=7²-1
T7=49-1
T7=48
thus the 11th term is 48
4] General sequence is T=1/3n². The term will be evaluated as follows:
plug in n=3 in the expression and simplify:
T3=1/(3×3²)=1/27
Thus the 3rd term is 1/27

Answer:
y=3
Step-by-step explanation:
The vertical sides of the rectangle must be equal
10 =2y+4
Subtract 4 from each side
10-4 =2y+4-4
6 = 2y
Divide each side by 2
6/2 =2y/2
3=y
Since radius of a circle is half of the diameter of the circle
so the radius is 4 inches
and 1 inch=2.54 cm so radius=10.16cm
